Calcium Carbide () is a widely used industrial starting material. Which of the following statements — s Block Elements Chemistry Question

💡 Solution & Explanation

Hydrolysis of $CaC_2$ yields acetylene ($HC \equiv CH$). The carbide ion is isoelectronic with $N_2$ and has a triple bond (1 $\sigma$, 2 $\pi$). Reacting it with $N_2$ gives Nitrolium ($CaCN_2 + C$). Unlike $SiC$, $CaC_2$ is an ionic (salt-like) acetylide, making C incorrect.
